Objective: To explore the relationship between the ideal cardiovascular health behaviors and factors and newonset heart failure. Methods: It was a prospective cohort study. People who attended the 2006-2007 physical examination of Kailuan Group Company and with complete data of cardiovascular behaviors and related factors were eligible for this study. A total of 95 167 participants who were free of valvular heart diseases, congenital heart diseases and a prior history of heart failure were included. Basic cardiovascular health score (CHS) of each participant was calculated. Participants were divided into 3 groups according to CHS. Group 1:CHS<8 (n=26 640), Group 2:8≤CHS<10 (n=35 230), Group3:CHS≥10 (n=33 297). The general clinical data and laboratory test results were collected. The outcome was defined as the first occurrence of heart failure at the end of followup(December 31, 2016). Cox regression model was used to determine the association between baseline CHS and the risk of newonset heart failure. Results: After a median followup of 10.3 years, the incidence of newonset heart failure in the group of CHS<8,8≤CHS<10,CHS≥10 were 2.7%(729/26 640), 1.8%(651/35 230) and 1.1%(360/33 297),respectively. After adjustment for age, sex, history of myocardial infarction, history of atrial fibrillation, income, alcohol consumption, education and the use of antihypertensive, cholesterol-lowering, glucose-lowering medications, compared with the group of CHS<8, the Cox regression model showed that HRs of the group of 8≤CHS<10 and CHS≥10 were 0.68 (95%CI 0.61-0.75), 0.49 (95%CI 0.43-0.55), respectively. Cox regression analysis after removing each single cardiovascular behavior or factor showed that the HR value range ability was as follows:systolic blood pressure(HR=0.78,95%CI 0.74-0.82), body mass index(HR=0.78,95%CI 0.74-0.82), fasting blood glucose (HR=0.77,95%CI 0.73-0.81), total cholesterol(HR=0.76,95%CI 0.72-0.80), physical exercise(HR=0.72,95%CI 0.69-0.76), smoking(HR=0.75,95%CI 0.71-0.79) and salt intake(HR=0.73,95%CI 0.69-0.77). Conclusion: CHS is negatively associated with the risk of newonset heart failure, and there is a dose-response relationship between the two indexes.
目的： 探讨理想心血管健康行为与因素与新发心力衰竭（心衰）的关系。 方法： 该研究为前瞻性队列研究。入选2006至2007年参加开滦集团公司职工健康体检且心血管健康行为与因素资料完整者作为观察对象，排除患有瓣膜性心脏病、先天性心脏病以及有心衰病史者。依据心血管健康评分（CHS）将入选人群分为CHS<8分组、8分≤CHS<10分组和CHS≥10分组。以新发心衰为终点事件，研究随访至2016年12月31日。采用多因素Cox回归模型分析CHS与新发心衰的关系。 结果： 该研究最终入选95 167人，其中CHS<8分组26 640人、8分≤CHS<10分组35 230人、CHS≥10分组33 297人。中位随访时间10.3年，随访期间CHS<8分组、8分≤CHS<10分组和CHS≥10分组人群心衰发病率分别为2.7%（729/26 640）、1.8%（651/35 230）和1.1%（360/33 297）。在校正了年龄、性别、心肌梗死史、心房颤动史、收入、饮酒、教育水平以及服用降压药、降糖药、降脂药的情况后，多因素Cox回归分析结果显示8分≤CHS<10分组和CHS≥10分组人群新发心衰的风险分别较CHS<8分组低了32%（HR=0.68，95%CI 0.61~0.75）和51%（HR=0.49，95%CI 0.43~0.55）。从理想心血管健康行为与因素中分别移除1个行为或因素，多因素Cox回归分析结果显示，HR值变化幅度从大到小依次为收缩压（HR=0.78，95%CI 0.74~0.82）、体重指数（HR=0.78，95%CI 0.74~0.82）、空腹血糖（HR=0.77，95%CI 0.73~0.81）、总胆固醇（HR=0.76，95%CI 0.72~0.80）、体育锻炼（HR=0.72，95%CI 0.69~0.76）、吸烟（HR=0.75，95%CI 0.71~0.79）和食盐摄入量（HR=0.73，95%CI 0.69~0.77）。 结论： CHS与新发心衰风险呈负相关，并呈现剂量-反应关系。.
